Setting agent protocol is deprecated

[necipakca]

Apparently it is deprecated to set agent protocol.

thanks for the report, it's something we need to investigate

There is some info about this on the upgrade guide to new LTS versions:
https://www.jenkins.io/doc/upgrade-guide/2.492/#removing-configurability-of-jenkins-agent-protocols-list

Removing configurability of Jenkins agent protocols list

The list of agent protocols is no longer configurable through the GUI or the Configuration as Code (JCasC) plugin. Going forward, there are two protocols: one for inbound TCP agents and a ping protocol used to test connectivity. The agentProtocols section of a configuration as code global configuration should be deleted because it will now be ignored. If you do not wish to allow inbound TCP agents, disable the port instead of the protocol.

I think this project needs inbound TCP agents to run jobs? So eventually removing would be enough to fix the warning?
